/* bench/mem_watch_sim.c — 宿主「边播监控取证」阈值/峰值验证（agent 32bit OOM 取证）。
|
||
*
|
||
* 归属演进（2026-09-02 定案，ARCHITECTURE_PRINCIPLES ③混合）：**降载决策上收通用层**——
|
||
* A + C 分别归 SDK meow_cachegov / meow_svc_perf；本 sim 只验证 mem_watch 的**取证**语义：
|
||
* 三档 level 标注滞回（normal→high→critical→滞回→normal）+ song_end 重置峰值 + song_begin 起算。
|
||
* （旧版「dl_paused/prefetch_paused 降载断言」已随降载上收移除——那由 meow_cachegov_sim
|
||
* 与 svc_perf test_cachegov_monitor 覆盖。）
|
||
*
|
||
* 依赖：仅 app/play/mem_watch.c（+ meow_log 桩）。
|
||
* 编译（ncm_app 目录下）：
|
||
* gcc -O2 -Wall -Wextra -DJSMN_HEADER -I. -I../sdk -I../meow_launcherd \
|
||
* -c bench/mem_watch_sim.c -o /tmp/mw.o
|
||
* gcc -O2 -Wall -Wextra -I. -I../sdk -c app/play/mem_watch.c -o /tmp/mw_mod.o
|
||
* gcc -O2 -o mem_watch_sim /tmp/mw.o /tmp/mw_mod.o -lpthread -lm
|
||
* 运行：./mem_watch_sim （exit 0=PASS / 1=FAIL）
